Abstract: 429,570. Television. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Ives, H. E. ; 32, Laurel Place, Montclair, New Jersey, U.S.A.) Nov. 30, 1934, No. 34412. Convention date, Dec. 1, 1933. [Class 40 (iii)] A continuously moving motion picture film 6 is scanned longitudinally by light from a source 4 passing through a collimating lens 5, a scanning disc 1 having a spiral row of apertures or lens L1- L50 and through an oblique aperture 3 in a baffle 2, the scanning means being so arranged and the aperture so dimensioned and located that each picture frame is completely scanned before scanning of the succeeding picture frame is commenced. The beams from the lens 11 which receives the light transmitted through the film may either converge or diverge on to the photo-electric cell 12. When, as shown, the scanning beam moves in a direction opposite to that of the film, the first and last lenses in the disc 1 lie on the same radius of the disc and the spacing between lenses is made somewhat less than the vertical dimension of a frame of the film. When, however, the scanning beam moves in the same direction as the film, the spacing between lenses is slightly more than the vertical dimension of a frame and the angular spacing of the first and last lenses is twice that of any other two successive lenses. A scanning cylinder may be employed instead of a disc.

Abstract: 587,388. Helicopters. AUTOGIRO CO. OF AMERICA. July 26, 1944, No. 34507/46. Convention date, July 27, 1943. Divided out of 587,359. Drawings to Specification. [Class 4] A rotary-winged aircraft has a sustaining rotor in which the hub is controllably tiltable in one vertical plane only and control of the aircraft in the vertical plane perpendicular to the first-mentioned vertical plane is obtained by means of cyclic pitch control of the rotor, of variable amplitude and algebraic sign and of invariable phase such that the maximum and minimum pitch angle positions are in the first-mentioned vertical plane. In the construction described, the plane in which the hub is tiltable is the fore-and-aft plane of the craft and the construction for controllably tilting the hub is as described in Specification 587,359. The cyclic pitch control whichis exercised by means of the control stick C (also used for the hub control), (see drawings of Specification 587,359), acts through a torque tube Y to. operate a Bowden wire 47 for causing tilting of a,pivoted disc 41 carrying rods 40 jointed to arms 11 for turning the rotor blades to change their pitch. The rotor blades may be free to flap. Specifications 393,976 and 410,532 also are referred to.

Title: Improvements in transistor circuits for pulse & surge production
IPC: H03K3/30
Filed: 1958-10-29
Abstract: 864,959. Transistor pulse generating circuits; keying carrier frequencies. SNEATH, O. B. Oct. 28, 1959 [Oct. 29, 1958]. No. 34570/58. Classes 40(5) and 40(6) In a transistor squegging oscillator circuit, the squegging rate is varied by means of a potentiometer, the moving contact of which is connected to the end of the timing capacitor connected to the base, the ends of the potementior being connected respectively to a voltage source and through a capacitor to a point of fixed potential with respect to the emitter. Fig. I shows a squegging oscillator in which the base end of the timing capacitor Cl is connected to the tap on a potentiometer R1 so that when the potentiometer slider is at the lower end the capacitor C2 is effectively in parallel with Cl and the whole of R1 is effective so that a slow squegging rate results. When the potentiometer slider is at the upper end the capacitor C2 is ineffective and the potentiometer resistance is removed from the timing circuit so that a much higher squegging rate is produced. A pulse output which varies either side of the positive supply potential is obtained from a tapping on a potentiometer R6. The squegging may be interrupted by connecting damping circuit C4, R4 across the transformer secondary winding. Connecting of the damping circuit may also be made to the upper end of C2 instead of Cl so that when the potentiometer slider is in its lowest position the damping circuit becomes effective. A wider range of pulse repetition frequency may be obtained by connecting further capacitors between the positive supply and taps on potentiometer resistor R1 (Fig. 2, not shown).

Abstract: 1,249,642. Magnetic structures. HONEYWELL Inc. 19 July, 1968 [9 Aug., 1967], No. 34675/68. Heading H1H. [Also in Division C7] A magnetic memory carrier bears a magnetic thin film having a uniform distribution of partsphere protrusions of diameter between 0.3 and 20 Á, preferably 1 to 4 Á. As described the carrier is a Be-Cu wire which has been electroplated with copper so as to produce a "caviar"  surface (see Division C7), a thin film of non- magnetostrictive Ni-Fe alloy being uniformly electrodeposited thereover. Reference is made to the use of a non-ferromagnetic material other than copper such as electroless nickel or gold to form the " caviar " surface and also vaguely to using more than one layer of deposited material including material with dielectric, conductive or adhesive properties in the formation of the " caviar " finish. Magnetic films having such a finish provide better characteristics as regards output and disturbance sensitivity compared with smooth films.

Abstract: 1424460 Composite coated containers: coating apparatus DART INDUSTRIES INC 20 July 1973 [24 July 1972] 34837/73 Headings B2E and B2L A process for manufacturing composite glass and plastics containers comprises heating a moulded glass container portion to 350 to 450‹C, coating an area of it with chemically adherent, resilient, thermoplastic polymer particles and fusing the particles to form a flexible resilient coating on the glass container portions. In a preferred process, glass bottles are preheated in an oven arranged in ranks on a conveyor (Fig. 1, not shown), then rearranged into single file onto a further conveyor 22. A screw feeder 24 feeds bottles to a transfer tractor belt device 26 which conveys the bottles through an electrostatic spray booth 12 having apertures 54 providing access spray guns and which is cleaned by a plurality of vacuum stations 38, 40, 42, 44. A fluidised bed 48 feeds the spray guns and also receives excess particles through an aperture in the floor of the booth 12. The bottles are then heated in an oven and cooled by forced draught. Several pairs of spray guns may be provided in the spray booth, the guns at each pair being directed to one another from opposite sides of the booth, and the sprays from the guns being segregated by an air curtain to facilitate multiple coating of the bottles. It is stated that a precoat of an emulsion or solution of thermoplastics polymer may be applied. Once the bottles have cooled after sintering the coating may be provided with a lubrication layer of a wax composition, or alternatively the coating is subjected to flame treatment to facilitate application of labels. Preferred coatings are ethylene homopolymers and copolymers with acylic acid, methacrylic acid, ethacrylic acid, crotonic acid, fumaric acid, maleic acid, itaconic acid, vinyl sulphonic acid, maleic anhydride, mono-methyl maleate, mono-ethyl maleate, mono-ethyl fumarate, and mono-ethyl fumarate.

In the first case, the taping basket is driven at a at constant speed, while the magazine holder is braked at b when a change is made from an empty reel to a full reel. The braking device is controlled through a tape storage means, not illustrated. In the second case, the magazine holder is driven at b with constant speed subject to regulation by a detector 9, and the taping basket 1 is driven at a with constant torque. When a reel is changed, the magazine holder 2 is regulated through the detector 9 which compares a predetermined speed of rotation with that of the taping basket.
